Produced by Vogue Wright Studios, "The Long Corridor" is a 1955, black and white film about the Zenith company and the manufacture of high quality television sets. We follow a lonely night watchman through a long corridor as he enters different doors representing the different divisions of the Zenith company.
The movie opens with a train barreling through the night. A night watchman enters the frame. He turns and walks up the stairs. He walks the halls with a flashlight.

The camera pans to a door that says “Solid State Physics” 152. The watchman enters. Physicists work in the lab 2:30. A man uses an x-ray machine to x-ray common salt changing its chemical makeup 3:00. The camera pans across machinery until we see that it is freezing liquid helium 3:35. A man observes a giant electromagnet 3:55. We are back with the watchman in the corridor 4:20. He comes to a door named, “Research” 4:30. His flashlight scans the room 4:46. We now see people working within the room. A man stands at a blackboard in front of a group of students/researchers 5:10. The camera pans across the researchers’ desk. Dr. Robert Adler is pictured - he designed the 6AR8 color separation tube used in color TVs. An animation illustrates how it functions 6:00.

Phonograph cartridges are checked for quality sound 12:22. FM tuning requires extreme accuracy and stability 13:20. Testing is very important 13:27. Temperature testing occurs to make sure all components work within a certain range 14:00. At any time a completed unit may be pulled from the assembly line for random inspection 14:43. A booth is set up with TVs to receive signals at varying distances 15:10. The glass safety screen of the TV is subjected to a violent impact test 15:55. Set is subjected to jarring and shaking - such as it might experience under normal delivery circumstances 16:15. The watchman walks the corridor again 16:24. He comes to the next door, “Field Testing” 16:32. A 3-D map of the United States is shown on the wall 16:53. A rural locale is chosen for the field test, far away from the television receiver 17:30. Zenith performs a sensitivity test to see how the picture will come through at great distances 18:10. Zenith also tests in urban areas with strong signals that may conflict and overload affecting reception 18:54. Zenith TV working perfectly although directly under a police radio antenna 19:40.

Zenith company was founded by Ralph Matthews and Karl Hassel[4] in Chicago, Illinois, as Chicago Radio Labs in 1918. The name came from ZN'th, a contraction of its founders' ham radio call sign, 9ZN. The first Zenith television set appeared in 1939, with its first commercial sets sold to the public in 1948. The company is credited with having invented such things as the wireless remote control and FM multiplex stereo.

Old Nightwatchman: "Look at all this Captain Whiz Bang and Buck Rogers stuff! "
that scope reminded me of outer limits
Zenith was my favorite brand back in the '70s. They merged or cooperated with Heathkit to make computers (fully assembled, so so much for Heathkit), and both went under water not long after. They were shrimps in that industry and would both have been better off not bothering. I do miss both companies to this day, but as one poster mentioned, they went offshore (long before NAFTA) and suffered the loss of dignity and customer allegiance. Zenith more than Heathkit. Heatkit's problems were more that they tried to drive their market more toward pre-assembled things, thus losing their base. Such a shame.
My in laws had a big Heathkit console color TV that the young woman who eventually became my wife built in the summer of 1976. They got 20 years out of it.
She went on to get a Bachelors in Electrical Engineering, on a 4 year USAF ROTC scholarship, commissioned an officer, and earned an MSEE at the Air Force Institute of Technology. She's now a civilian engineer in the US Navy's aircraft flight test division..
Kids growing up today will never know a world where companies respected costumers and used science. It's a shame the world turned into such a dystopian nightmare.
FYI, Zenith is now owned by SG of Korea .
Almost every scene is has a modern-day OSHA violation. Just look at those soldering irons!
Back when industrial films where not cringe, and felt like they where actually trying to make something that was cinematic quality.
The president was trying to recover this sort of American progression.
It was working
3.57MHz crystal made B&W compatible with color signal. It would be 1965 when color TV's hit the market and RCA led the development. B&W TV's still made half the sales until the mid 70's, and where sold well into the 80's.
The president was trying to resurrect this American spirit.
